About 1 Bit Survivor
1 Bit Survivor is a turn-based survival horror roguelike with stylized pixel art. A deadly virus has transformed the citizens into flesh-eating mutants, and you have 28 days to reach a distant bunker before the military nukes everything above ground. You move and shoot using simple controls, while limited resources make each decision matter.
Survive the journey
You get only one chance to survive: death ends the run. Randomized items let you upgrade your character, and you can choose from three unlockable classes to shape your play style.
